Heralding Deal with China, Philippines Restarts Offshore Oil-Gas Exploration in Disputed Sea Ralph Jennings TAIPEI, TAIWAN - The Philippine government's lifting of a ban on offshore oil and gas exploration reopens the door to joint energy development with China, the erstwhile biggest player in a regional maritime sovereignty dispute, analysts believe. Philippine President Rodrigo Duterte has approved a Department of Energy proposal to resume exploration in the South China Sea, the department said October 15 in a statement online. Exploration was called off six years ago as a Sino-Philippine maritime dispute peaked. Resumption of oil and gas exploration will "infuse the economy with fresh foreign direct investments," Energy Secretary Alfonso Cusi said in the statement. China stands to become the key foreign investor despite irritating the Philippines and five other governments with its maritime expansion since 2010, analysts say. They chafed particularly after officials in Beijing authorized the landfilling of tiny islets, in some cases for military use. China claims about 90% of the sea, including tracts that the Philippines say come under its exclusive economic zone. Two years ago this month, China and the Philippines signed a memorandum of understanding to look together for undersea oil and gas, a way of defusing their corner of the broader regional dispute. The Sino-Philippine dispute culminated in 2016 with a Philippine world arbitration court victory. China snubbed the ruling, but that same year Duterte moved to make friends with counterparts in Beijing and tap it for economic aid. "Early on, the [Duterte] administration entered into memoranda of understanding with China, and that included joint development, or at least the promise of joint development, as far as the West Philippine Sea is actually concerned. So this might simply be moving forward on those MOUs, especially since the Duterte administration is winding down," said Herman Kraft, political science professor at University of the Philippines Diliman. The West Philippine Sea is Manila's term for the South China Sea. .
